narrow. Maxillary extends slightly beyond nostril, though not 

 nearly to eye, and slips below preorbital. Teeth rather slender, 

 somewhat compressed, pointed, crowded close to form an even 

 cutting-edge in a single row. No teeth on mouth roof or on tongue. 

 Inner buccal folds broad. Tongue thick, fleshy, apparently free in 

 front. Nostril small pore about midway in snout length. Inter- 

 orbital evenly convex. Preorbital broad, width about If in eye, 

 ends behind in broad posteriorly directed spine. Lower suborbital 

 and hind preopercle edges serrate, serrse on latter graduated longer 

 below, and lower preopercle edge entire. Opercle with 2 blunt and 

 inconspicuous spines, upper concealed by scales. 



Gill-opening forward about opposite front eye edge. Rakers 

 6+13, lanceolate, about half length of filaments and latter 1| in eye. 

 Pseudobranchise long as gill-filaments. Brancliiostegal membrane 

 short fold over short and constricted isthmus. 



Scales finely ctenoid, largest over middle of side of trunk and 

 become much smaller all about edges, in lengthwise rows parallel 

 with upper arch of lateral line. All larger scales narrowly imbricated. 

 All fin bases scaly. Short scale between ventral bases about f 

 length of spine. Suprascapula with 3 blunt points. Exposure of 

 humeral scale little larger than pupil. Axillary ventral scale broad, 

 pointed, I length of spine. Cheek with 3 rows of scales. Sub- 

 orbitals, preorbital, snout edge, hps and chin naked. Upper arch 

 of 1.1. extends below front dorsal rays, concurrent with upper limit 

 of squamation on dorsals. Tubes large, simple, and each extending 

 well over scale exposure. Pores in straight section small, incon- 

 spicuous, simple or double irregularly, and not on caudal base. 



Spinous dorsal origin about opposite that of pectoral, spines all 

 more or less subequally high, edge of fin notched and slight cutaneous 

 flap behind each spine tip. Soft dorsal inserted about last third in 

 space between upper hind preopercle edge and caudal base, fin 

 rounded with median rays longest. Anal inserted about midway 

 between pectoral origin and caudal base, first spine about I of second. 

 Soft anal similar to soft dorsal. Caudal deeply emarginate, upper 

 lobe much larger, 3| in combined head and trunk. Pectoral broad, 

 about long as upper caudal lobe, reaches hind edge of vent and 

 upper rays longest. Ventral inserted close behind pectoral base, 

 reaches anal, and spine slightly over half length of fin. 



Color in alcoholjlargely chocolate-brown above and posteriorly, 

 head, breast and belly anteriorly paler or faded in appearance. 

 Iris slaty. Dorsals and anals blackish-brown. Caudal pale brown-
